The Mario Channel: MARIO'S CHALLENGE is the thirty-fifth episode of Season 7 and the TBA overall to be uploaded by SMG4.
Mario has challenged EVERYONE IN THE SMG4 UNIVERSE to climb his tower full of trials and obstacles! WHO WILL MAKE IT TO THE TOP!?
The video begins at Mario's castle with many people gathered at its base. Via a monitor, he introduced everyone to his ultimate challenge, where he invited all of them to try and win it. Both Toad and Wario asked where was the money which he had promised to all of them. However, Mario said he had something even better. Luigi hoped it would be a magical unicorn but Mario told him he was wrong. Instead, it was inside a mystery box he held in his hand and was the grand prize for winning the challenge. Mario warned there would be a lot of obstacles on the way to the top, getting Meggy, Bowser, and Dr. Pootis excited but frightening Luigi and Fishy Boopkins. Just before he opened the gates, Mario told the participants to try to avoid dying because he would not be covering any medical bills.
Floor 1: The Pit (120 participants remaining)
The first floor had a big hole called The Pit. Mario wanted to see who could jump just like him. Not being deterred, SMG4 proceeded to jump across the pit but fell short and ended up falling into the pit. Other contestants then started to mindlessly just fall into the pit, but Professor E. Gadd easily cheesed the challenge by just flying across with his jetpack. As Wario wondered how he would clear the challenge, he saw Yoshi leaning over the pit. Deciding to use Yoshi as a steed, he jumped on him. Unfortunately, he crushed the dinosaur's legs due to his weight, paralyzing him. Fearing the repercussion, he walked backward away from Yoshi. In a bid to cross the pit, multiple Goombas used their stack formation to make a bridge across the pit. As they reached the other side, they wondered how they would get up from the other side. Soon, Gourmet Guy crossed the bridge but his weight caused both him and the stack to fall into the pit.
Floor 2: The Slope (79 participants remaining)
The second floor was a huge slope. The participants had to get to the top of the slope while dodging the random items tossed by a retro Donkey Kong. Toadsworth tried climbing to the top but was knocked down by several barrels. Luigi expertly jumped across multiple barrels but was knocked down by Wario, although neither was eliminated. Link casually danced his way up singing Stayin' Alive while nearby, several Koopa Troopas were being knocked down by the barrels. Bowser also climbed to the top but called everyone a loser as he had an ingenious plan: Use his shell to bounce off the objects. Both Bob and Boopkins also made it to the top but only because Bob was using the spike as a meatshield.
Followed closely after was Waluigi. He, however, saw a huge object coming his way and grabbed a pole to cling onto. A few more heavy objects soon came and smashed his face a few more times, causing him to let go and be eliminated. Towards the end of the segment, Professor E. Gadd tried cheesing the floor using his jetpack again but got hit by a chair, eliminating him.
Floor 3: The Gargoyle (62 participants remaining)
Mario introduced the participants to his friend, Gobbles The Gargoyle. To pass this floor, they had to make him laugh. If they bored him, they would fail and be eliminated. Wario went first by doing a slapstick comedy of throwing a pie at Luigi's face. Gobbles laughed and allowed both of them to continue. Frankie went next and started to sing a song about his "dingaling", confusing Gobbles into crushing him. Boopkins was next. Naturally worried, he quickly came up with a plan to have Gobbles laugh: A tap-dance. Bowser then saw what Boopkins was doing and claimed he could do better by tap dancing faster. This led to a tap-dance off with both of them eventually dancing so fast they were set ablaze. Pleased with the dancing, Gobbles laughed and let them through. Finally, Bob wanted to pass, saying it would be very easy as he claimed he did entertainment for a living. He told a joke. Not only was the joke cheesy and very bad, but Bob's punchline was also actually an insult to Gobbles. Bob thought it was funny but Gobbles thought otherwise and promptly crushed him too.
Floor 4: The Bullseye (58 participants remaining)
In the fourth floor, Mario wanted to test each participant's aim. To pass the floor, within three shots, they must aim a faraway target's bullseye. Failed and they were eliminated. Mr. Blizzard was the first to shoot but his shot hit a nearby Koopa Troopa, killing him. Meggy, being a skilled shooter, looked at another direction as she fired her gun, causing the shot to hit the bullseye easily. Shocked at what he witnessed, Heavy Weapons Guy claimed it was impossible, with Meggy just responding with a peace sign. Not being deterred, he proceeded to fire his gun, a sniper rifle but it hit the glass behind. He fired again but the shot headshot a nearby Goomba, killing him. Furious, Heavy proceeded to use a minigun to fire at the bullseye. However, since he was clearly over the three bullets limit, Mario proceeded to kick him out of the firing range, eliminating him before stating he was dead. Finally, Toad proceeded to do a 360 no-scope but aimed wrongly at Bowser, causing him to get furious. He retaliated by setting Toad on fire, which Mario commented as "That's a spicy meat-a-ball!"
Floor 5: The Mushroom (41 participants remaining)
The fifth floor was a jumping course consisting of mushroom platforms. Mario warned the participants that some of the mushrooms were traps or unstable. Toadette was the first participant to jump across the course but activated a trap, causing the mushroom platform to ram her onto the ceiling, eliminating her. Peach Toadstool was hanging onto a mushroom platform for dear life but was kicked to her presumed death by Swagmaster69696969696, who apologized for what he did but said he had to win. Suddenly, Dr. Pootis jumped onto the platform he was on, causing it to sink into the lava. Realizing what he did, Swagmaster fought Dr. Pootis for causing both of them to lose the challenge.
Nearby, SMG3 jumped across several platforms but landed on an unstable one. It fell into the lava but he was not eliminated yet. Seeing a nearby platform, he did a super jump towards it but was stomped on by Bowser who used him to get onto the platform, eliminating him.
Floor 6: The Maze (34 participants remaining)
On the sixth floor, the participants were told to navigate a maze of rooms. However, some of the rooms had scary things in them and if they got caught by such stuff, they would be eliminated. X opened a door which revealed to have a human Barney in it. Seeing him, Barney went off to hug X but the door shut before he could do so. Bowser tried another door but what he saw in the room shocked him, which was revealed just to be Wario picking his nose. In response to Bowser's reaction, Wario flipped him off.
As Boopkins wandered for a way out, he entered the room and found a Dead Hand from The Legend of Zelda: Ocarina of Time, which proceeded to chase after him. Just as Boopkins thought he was done for, he saw a banana and tried to deter Dead Hand with it. Suddenly, Donkey Kong appeared. Thinking he was there to save him, Boopkins was relieved. However, it turned out Donkey Kong just wanted the banana Boopkins was holding and snatched it. He ate it and then left the room happy. Boopkins then tried asking Dead Hand if it wanted to see him tap dance but he obviously refused and it eliminated Boopkins offscreen.
Floor 7: The Wheel (23 participants remaining)
Mario introduced the participants to the wheel which would randomly select a small challenge with one of the options to even instantly winning the challenge. A Piranha Plant was the first participant to try the wheel and its challenge was to survive an intense meteor shower. Piranha Plant was ready for it but was naturally killed by the meteor shower. Wario then pushed Luigi to do the wheel which gave him the challenge to do absolutely nothing, allowing Luigi to pass the floor. Frustrated by Luigi's lucky pick, Wario tried the wheel himself. It almost landed on surviving while being pushed off a plane but Wario pushed the wheel to select surviving free money. Thinking it would also be easy, Wario exposed his body for the money. Turned out it was being fired with huge coins at full force, which resulted in him crushed. Then, it was Link's turn. His challenge was to sing a beautiful song. Link chose to sing I Will Always Love You by Whitney Houston but sang it so horribly that it caused everyone's ears to bleed and for the monitor Mario's face was on to crack. In response to the awful singing, a train ran him over, eliminating him.
Floor 8: The Gauntlet (Ya'll gonna die (less than 20) participants remaining)
The eighth floor was a long obstacle course that had an elevator that would take the participants to the castle's roof. However, only one person was allowed in the elevator, causing all participants to quickly clear through the obstacle course. X, a Goomba, and some participants tried making a mad dash, just to activate a trap to their elimination. Luigi though managed to stop safely. In another section, Po came across a saw-blade but realizing it was too risky to cross, saw a Whomp and used it to shield himself from the saw blade. As he laughed at his cunning plan, another trap activated, pushing him off.
Steve in a third section saw some blades swinging. Going "YOLO!", he dashed across, just to have his head fall off after a while. In the fourth section across a bridge, a Shy Guy was crossing it when he was pushed off by Bowser. Once he crossed the bridge, he proceeded to destroy it just as Meggy was using it. As it fell, she used her quick reflexes to jump across the debris of the broken bridge to eventually cross the other side, bouncing on the Koopa King's head on the way, shocking and confusing him. The remaining participants eventually saw the elevator in a simple corridor. Mario then reminded them that only one participant was allowed in, causing everyone, including Dr. Eggman to rush for it. On the roof, Mario heard someone coming up to the roof. He turned around to see who was the fastest. It was revealed to be an anthropomorphic mushroom boy scout and former demon hunter named Shroomy. Mario was shocked at the newcomer but then brushed it off, saying that Shroomy had not won yet due to having one more challenge left: Mario himself in a tank.
Roof: The Italian (1 participant remaining)
The showdown between Mario and Shroomy began, taking place on top of the castle's roof. Suddenly, Shroomy brandished a rocket launcher, which surprised Mario, as he did not recall placing one in any of his challenges at all. Shroomy then revealed he was a rocket launcher builder and had a badge about it. He then fired a rocket at Mario, causing him and his tank to explode, killing him. Shroomy won the challenge and got his prize from the mystery box, which was actually a 10% off chicken nuggets at McDonald's coupon which would expire tomorrow. He proceeded to pin the coupon onto his badge holder and celebrated by dancing with his hands in the air. This continued into the credits, breaking the fourth wall.
